. s 1 This invention relates to improvements in packaging andit has particularreference to a formation of loaves or bricks of material and the assembly thereof in a shipping package. a a

In the production of loaves of cheese and other similar loaves or bricks wherein the material when initially packaged is in a more or less fluid 'state,"considerable difficulty has been experienced in attempts to use paper board or other semirigid containers instead of wooden boxes'and the like in'which to pour the material and in which the loaves or bricks are molded. Materials such as cheese are of a relatively heavy character and tend to bulge out the side walls of paper board receptacles such as it would otherwise be practicable to use. V I V Y The main objects of theinvention are to provide an arrangement whereby a semi-rigid paper 1 Olaiin. (Cl. 206-66) board receptacle may be successfully employed for the molding of the loaves of cheese or other material'; to'provide a package arrangement which, while serving to facilitate the packaging or material in paper board receptacles, also adapts the packaging to shipping purposes without enclosing the package in an extra "or species shipping contain'er; to provide improve packaging or the character indicated which will be economical and low in cost; and in general it the object of the invention to provide an improved packaging or the character indicated. I

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawings (2 sheets) wherein there is illustrated packaging embodying 9. Selected form of the invention.

-The present disclosure is with reference 'to the formation of a shipping package comprising five 5-pou'nd loaves of cheesebutit is to be under-; stood 'that this disclosure is merely typical and that the'i nvention is not restricted to the packaging of this particular kind of material.

Each loaf of cheese or other material is formed in a rectangular paper board receptacle desig- 2 1 nated 8 and shown in its entirety in Figiire'l. Each receptacle 8 is preferably formed'orf a suit= able grade of corrugated'paper board embodying an intermediate corrugated ply and inner and outer smooth faced plies of paper, such coin- 'posite'paper board beingcommon'ly used in the formation of shipping containers.

The containers 8' may be formed from a single sheet of material suitably scored to provide a bottom wall 9, opposite elongated side Walls [0 and H, opposite end walls l2 and 13- extending from the bottom wan 9 and'efld wan caps 14 and lliextending from the side Wall l'0,'- andl6 and H extending from the side wall H. The overlapping end walls and flaps are of course suitably united preferably adhesively to maintain the receptacle in the rectangular form shown in Figure 7.

For [forming the five loaf package herein illustrated, five of the receptacles shown in Figure 7 are filled wit-h the cheese or other material, the receptacles being first preferably lined with a suitable moisture proof sheeting which, after the receptacle is filled, is closed over the open top of the receptacle and sealed so as to produce an impervious enclosure for the paf kage content. The details of the liningsheet and its sealing form no part of the present invention and therefore will not be explained further.

A series of such filled receptacles which are respectively designated t8 (see Figure 4) are placed side by side, that is, with their elongated sides against one another, and they are placed with their open tops down on a cover sheet desig= hated l9, substantially as shown in figure .2. The cover' sheet 19 is also preferably formed of corrugated paper board embodying an intermediate corrugated paper ply and inner and outer sr'nooth paper piles and it is suitably creased or scored as indicated by the dot and dash lines 20"20 (Fig. 1) to provide side flaps 2|, 2|, and end flaps 22,22, which are 'f'ol'dable relative to the intervening hottofn wan portion 23. There is also formed by the scoring, naps '24', '24, the same extending outwardly from the long edges of the side flap 2|,2l,

As shown in Figure 2, the filled receptacles are placed on the bottom wall 23 Of the cover sheet [9 in such position that the side and end flaps 2'! and '22, respectively, may be folded upwardly and adhesively united to the respectively adjacent side end walls of the series of packages T8.

The flaps 24 are then folded inwardly over the then top walls of the packages l8 and adhesively united thereto, so that the package assumes the that the filled receptacles l8, l8 are placed in inverted position on the cover sheet I9. However, it will be understood that it is not essential that the units l8 be inverted and placed on the cover sheet but that the cover sheet mayinstead be placed over the tops of the units IS, the latter remaining in upright position, the side and end walls 2| and 22 being folded downwardly and adhesively united to the respective adjacent sur-. faces of the units l8, after which the flaps 24, 24 may be folded inwardly and under the units for adhesive attachment thereto. The weight of the units l8 would, of course, serve to provide sulficient pressure to insure effective bonding between the flaps 24, 24 and the bottom portions of the units l8, and suitable holding or guiding means may be provided for maintaining the flaps 2| and 22 in tight contact with the respectively adjacent wall portions of the filled containers, even while the latter are maintained in travel from a filling machine or from a liner closing machine. A package embodying the described structure has been found to be adequate to Withstand the normal rough handling to which it is subjected during transportation from the manufacturer and packager of the package content to retail dealers or other recipients. The package is especially convenient in the hands of a retail dealer in that he is not required to pry apart any wooden box cover or the like but may remove from the package one unit of material simply by cutting off one section such as illustrated in Figure 6, it being necessary to out only the bottom Wall part 23, the side flaps 2|, and flaps 24 of the cover sheet, whereupon the unit I8 will be separated from the remainder of the package. For guiding such severance, suitable light crease lines or printed or other lines may be provided on the member Hi. It is then a simple matter to open the single unit so as to permit removal of the loaf of cheese or other material from ,the container 8.

The described packaging structure is especially advantageous in connection with the packaging of cheese which is generally sold by butchers who may use a knife fOr cutting a unit from the complete package and for opening the individual unit to efiect removal of the loaf of cheese from the individual receptacle 8. When the loaves of material are enclosed in an impervious wraptain the same in the desired flat condition. The wall portion 23 of the cover sheet |'9 serves in the nature of a tie member for preventing outward bulging of the outermost side walls of the assemblage of units I8 and the flaps 22, 22 adhesively united to such outermost side walls results in a two-ply structure or reinforced outer side wall which of itself tends to resist bulging under the weight of the package content.

The end Walls of the respective units |8 are initially of two-ply or reinforced construction,

per such as previously referred to, the wrapped loaf may also be removed from the paper board receptacle 8 for display and to facilitate the cutting of predetermined amounts from the loaf as may be called for by purchasers.

The described packaging structure causes the associated units to support one another so as to retain the desired flatness of their adjacent side walls and the application of the cover member IS with its down-turned end flaps 22, 22 serves to support the otherwise unsupported side Walls of the respective end units to mainand, being of relatively small expanse, require no extra support. However, the end Walls of the individual units are strengthened by the side .wall flaps 2|. .The' said side walls 2| serve the additional important function of covering up the small crevices remaining between adjacent receptacles and between adjacent edges of the end wall flaps I5 and H, or M and I6, of the individual receptacles 8. -Such covering of the crevices assists in thefmaintenance of a clean oo n package and also eliminates numerous exposed recesses 0r edges which are so apt to get caught against other objects.

It is preferred that the corrugations in the cover member I9 extend lengthwise ofv the panel 23, thatis, in such direction, that the corrugations extend transversely of the length of the assembled units I8, |8. It has been found that it is somewhat easier to sever the corrugated stockin the member I! transversely of its corrugations than lengthwise thereof. Hence when the corrugations are arranged in the manner designated, separation of a unit l8 from the remainder of the package structure is facilitated.

It will be apparent that the extensions 24, 24 of the cover member l9 maybe omitted if desired, and that other changes in the arrangement may also be made Without departing from the spirit of the invention, the scope of which should be determined by the following claim, the same being construed as broadly as possible, consistent with the state of the art.

Iclaim:

A shipping package comprising a plurality of relatively independent, substantially like package units assembled in side by side, co-planar alignment, each of said units comprising a filled fiber board box having a bottom, sides, ends, and an open top, the open tops of the boxes being disposed in the same plane, and a fiber board member having a main panel disposed across said co-planar open tops of the assembled units, side flaps extending from opposite edges of said panel and respectively folded into overlapping relation to opposite aligned ends of the units and united thereto, extensions on said flaps folded inwardly of andunited to the bottoms of said boxes, and end flaps folded into overlapping relation and united to the outer sides of the outermost unit boxes at the ends of, the assemblage, the co-planar, exposed box bottoms intermediate said extensions constituting an outer surface portion of the shipping package, and said panel, side flaps, extensions and end flaps constituting other outer surface portions of the package, the fiber board in said boxes and in said member being of such character as to adapt the package to handling and shipping like a package enclosed in a conventional corrugated or like fiber board packing and shipping box.
